About us

Founded in 1992, Dotan Maritime Industries' revolutionary kickup rudder is the brainchild of company founder Leonid Chernin who graduated from the prestigious, internationally renowned Leningrad Boat-Building Institute with a Ph.D. in Maritime Engineering, specializing in air-hydrodynamics, after 8 years of studies.

Following graduation, Dr. Chernin held the position of manager at a shipyard where local experts, together with experts from Chernin's alma mater and experts from the Leningrad Aircraft Institute, shared invaluable knowledge and experience in the field of boat design and construction with the enterprising and passionate-about-sailboats young graduate.

The result was what came to be known as the Samson rudder, subsequently renamed the Dotan kick up rudder.

No stranger to sailing, Dr. Chernin began pulling halyards and steering courses at the helm thirty-five years ago on Optimists at a yacht club that produced several generations of champions. Leonid's club offered the boy a wide diversity of boats to sail on. The boy's passion for sailing grew unstoppably. During the years, Leonid passed from one class to another: Cadet, 420, etc. The sailor notched up a number of victories in international events in Olympic classes: Flying Dutchman, 470, Soling and catamarans. His passion for racing and the successes he achieved in the sport provided a perfect cornerstone for the professional knowledge he later acquired in air-hydrodynamic sciences at the Leningrad Boat-Building Institute.

Dr. Chernin believes that combining science with testing new ideas and manufacturing can bring about spectacular results, as evidenced by the development of the Dotan revolutionary kickup rudder.

"Many years of learning, persistent effort and hard work disguise the simplicity of a technical solution such as the one provided by Dotan's revolutionary kick-up rudder system", says Dr. Chernin. Dotan Maritime Industries receives hundreds of complimentary letters from the rudder's users, evidence of the fact that the rudder effectively solves problems that have plagued the sport of sailing for years".
"Dotan in addition maintains direct contact with all correspondents, adds Dr. Chernin, "thereby providing a good QoS".

Dotan`s rudder benefits

  • Flick-of-the-Wrist Magic

    Dotan's conceptually brilliant rudder mechanism enables you to set the blade with a simple flick of the wrist.
  • Rudder Box: Constructed of Non-Corrosive

    Incomparably strong and matchlessly durable, using non-corrosive, composite materials which make the Dotan rudder box more steadier against dynamic loadings than aluminum boxes.
  • Blade Shape: NACA Hydrodynamic Profile 

    The Dotan rudder blade's profile is designed on the basis of the NACA 0009 hydrodynamic profile (National Advisory Committee for Aeronautics). The Dotan rudder blade's shape minimizes wave and inductive resistance.
  • Encountering obstacles

    When hitting underwater obstacles such as rocks, sandbanks, jellyfish, etc., the blade automatically kicks up.
  • Warranty

    Your Dotan rudder system comes with a 3-year limited warranty for the rudder box and with a 2-year limited warranty for the blade. The rudder box for Optimists has a 10-year limited warranty.
